RULES FOR SAFE OPERATION
DOUBLE INSULATION isa safety concept in electric power
tools which eliminates the need for the usual three wire
groundedpowercord and groundedsupplysystem.Wherever
there iselectriccurrent inthetoolthere are twocomplete sets
of insulationto protect the user. Allexposed metal parts are
isolatedfrom internalmetal motorcomponents withprotecting
insulation.
IMPORTANT - Servicing of a tool with double insulation
requires extreme care and knowledge of the system and
should be performed only by a qualified service technician.
For service we suggest you return the tool to your nearest
Sears Storefor repair.Always useoriginalfactory replacement
parts when servicing.
WARNING:

1. KNOW YOUR POWER TOOL. Read owner's
manual carefully. Learn its applications and
limitations as well as the specific potential
hazards related to this tool.
2. GUARD AGAINST ELECTRICAL SHOCK by
preventing body contact with grounded surfaces.
For example: Pipes, radiators, ranges,
refrigerator enclosures.
3. KEEP GUARDS IN PLACE and in working order.
4. KEEP WORK AREA CLEAN. Cluttered areas
and benches invite accidents.
5. AVOID DANGEROUS ENVIRONMENT. Don't
use power tool in damp or wet locations or expose

7. STORE IDLE TOOLS. When not in use tools
should be stored in a dry and high or locked-up
place - out of the reach of children.
8. DON'T FORCE TOOL. It will do the job better
and safer at the rate for which it was designed.
9. USE RIGHT TOOL. Don't force small tool or
attachment to do the job of a heavy duty tool.
Don't use tool for purpose not intended - for
example - A circular saw should never be used
for cutting tree limbs or logs.
10, WEAR PROPER APPAREL. Do not wear loose
clothing or jewelry that can get caught in tool's
moving parts and cause personal injury. Rubber
WARNING:
Do not attempt to operate this tool until you have

instructions, safety rules, etc. contained in this
manual. Failure to comply can result in accidents
involving fire, electric shock, or serious personal
injury. Save owner's manual and review frequently
for continuing safe operation, and instructing others
who may use this tool.
gloves and non-skid footwear are recommended
when working outdoors. Wear protective hair
covering to contain long hair and keep it from
being drawn into nearby air vents.
11. ALWAYS WEAR SAFETY GLASSES. Everyday
eyeglasses have only impact-resistant lenses;
they are NOT safety glasses.
12. PROTECT YOUR LUNGS. Wear a face or dust
mask if operation is dusty.
13. PROTECT YOUR HEARING. Wear hearing
protection during extended periods of operation.
14. DON'T ABUSE CORD. Never carry tool by cord
or yank it to disconnect from receptacle. Keep
cord from heat, oil and sharp edges.
15. SECURE WORK. Use clamps or a vise to hold
work. Both hands are needed to operate the
tool.

use common sense. Do not operate tool when
you are tired. Do not rush.
30. CHECK DAMAGED PARTS. Before further use
of the tool, a guard or other part that is damaged
should be carefully checked to determine that it
will operate properly and perform its intended
function. Check for alignment of moving parts,
binding of moving pads, breakage of parts,
mounting, and any other conditions that may
affect its operation. A guard or other part that is
damaged should be properly repaired or replaced
by an authorized service center unless indicated
elsewhere in this instruction manual.
31. DO NOT USE TOOL IF SWITCH DOES NOT
TURN IT ON AND OFF. Have defective switches
replaced by an authorized service center.

DEPTH OF CUT ADJUSTMENTS
See Figures 6, 7 and 8.
When routinga groove thatistoodeep tosafelycutinone pass,
itisbesttomake thecutinseveral passes. We recommend that
several passes be made to reach deeper cuts.
Properdepthofcutdepends on severalfactors: powerofrouter
motor,typeofcutterbeing used,andtype ofwoodbeing routed.
A lightweight,low power router isdesigned for makingshallow
cuts. A router with high power rating can safely cut deeper.
Small bits,suchas 1/4 in.shank veiningbitswith1/16 in.cutting
diameters, are designed to remove only small amounts of
wood. Large bits, such as 1/2 in. shank straight-flutebits, are
made to remove larger amounts ofwood ina single pass. Cuts
can be made deeper in softwoods, such as white pine, than in
tough hardwoods,like oak or maple. Based upontheseconsid-
erations, choose a depth of cut that will not place excessive
strain on router motor. Ifyou find that extra force is needed or
thatthe motorspeed slows down considerably, turnoff router
and raise the bit.Then, make the cut in two or more passes.
TO SET DEPTH OF CUT
1. UNPLUG YOUR ROUTER.
WARNING: 1
Failure to unplug your router could result in accidental
starting causing serious_injury.
2. Raise cutter by depressing plunge release actuator.
See Figure 6.

6. Squeeze plunge lock actuator to lock cutter at "zero"
depth of cut, NOTE: If desired, adjust depth control
knob until hex nut comes in contact with stop flange.
This will provide a positive stop at "zero" depth of cut.
7. Rotate depth stop block to desired position, loosen
lock knob, then turn adjustment knob until stop bar
touches stop screw on depth stop block.
8. Slide zero-reset indicator up or down the scale on stop
bar until white line on zero-reset indicator aligns with a
desired reference point. For example, align white line
with 1 in. mark on the scale.
9. Next, turn adjustment knob in the opposite direction,
lifting stop bar to obtain desired depth of cut. See
Figure 8. For example, if setting 1/8 in. depth of cut,
the zero-reset indicator will move 1/8 in. from the 1 in.
reference point. Tighten knob securely.
10. Position your router so that the cutter can extend below
the subbase for desired depth setting.
11. Depress plunge release actuator.

shown in figure 14.
Beforestarting router, make sure cutter is securely tightened
in collet nut and that depth of cut is properly set.
Turn router on and let motor build to its full speed, then
gradually plunge or feed cutter intoworkpiece. DO NOT let
the cutter contact workpiece before turning on router and
allowing it to develop full speed.
Remain alert and watch whatyou are doing. DO NOT operate
router when fatigued.
FEED DIRECTION
When routing, the cutter rotates clockwise. Therefore, you
should feed the router into the workpiece from left to right.
When fed from leftto right,the rotationof the cutter pullsthe
router against the workpiece. Iffed inthe oppositedirection,
the rotation forces of the spinning bit willtend to throw the
router away from the workpiece. This could cause loss of
control of your router.
RATE OF FEED
IMPORTANT: The whole"secret" ofprofessional mutingand
edge shaping lies in making a careful set-up for the cutto be
made and in selecting the proper rate of feed.
The proper rate of feed depends on several factors: the
hardness and moisture content of the wood, the depth of cut,
and the cutting diameter of the bit. When cutting shallow
grooves in soft woods such as pine, a faster rate of feed can
be used. When making deep cuts in hardwoods such as oak,
a slower rate of feed will be required.
The best rate of feed is one that does not slow down the router
motor more than one-third of its no-load speed. If the router
isfed too fast, itwilltake large chips out of the wood and leave
gouge marks. Ifthe router isfed too slow, itwill scorch orburn
the wood.
P_n_ 1_
PROPER FEEDING
OPERATION
The right feed is neither too fast nor too slow. It isthe rate at
which the bit is being advanced firmly and surelyto produce
a continuous spiral of uniform chips-- without hogging into
the wood tomake large individualchipsor, onthe otherhand,
to create only sawdust. If you are making a small diameter,
shallow groove in soft, dry wood, the proper feed may be
about as fast as you can travel your router along your guide
line. On the other hand, ifthe bitisa large one,the cut isdeep
orthe wood is hardto cut, the properfeed may bea very slow
one.Then, again, across-grain cutmay requireaslower pace
than an identical with grain cut in the same workpiece.
There is no fixed rule. You _ill learn by expedence from
practice and use. The best rate of feed is determined by
listening to the sound ofthe router motor and by feeling the
progress of each cut. If at all possible, always test a cuton a
scrap piece ofthe workpiece wood, beforehand.
FORCE FEEDING
Clean, smooth routing and edge shaping can be done only
when the bit is revolving at a relatively high speed and is
taking very small bites toproduce tiny,cleanly severed chips.
If your router isforced to move forward too fast, the RPM of
the bit becomes slower than normal in relation to itsforward
movement. As a result, the bit must take bigger bites as it
revolves. "Bigger bites" mean bigger chips, and a rougher
finish. Bigger chips also require more power, which could
result in the router motor becoming overloaded.
Under extreme force-feeding conditionsthe relative RPM of
the bit can become so slow -- and the bites ithas to take so
large -- that chips will be partially knocked off (rather than
fully cut off), with resulting splintering and gouging of the
workpiece. See Figure 15.
YourCraftsmanrouterisanextremelyhigh.speedtool (22,000
RPM no-load speed), and will make clean, smooth cuts if
allowed torunfreely without theoverload ofa forced (too fast)
feed. Three things that cause "force feeding" are bit size,
depth-of-cut, and workpiece characteristics. The larger the
bit or the deeper the cut, the more slowlythe router shouldbe
moved forward; If the wood is very hard, knotty, gummy or
damp, the operation must be slowed still more.
You can always detect "force feeding" by the sound of the
motor. Itshigh-pitched whine willsound lowerand stronger as
Lt loses speed. Also, the strain of holding the tool will be
noticeably increased.
TOO FAST
TOO SLOW Fig. 15
TOO SLOW FEEDING
Itis also possible to spoil a cut by moving the router forward
too slowly. When it is advanced into the work too slowly, a
revolving bit does not dig intonew wood fast enough to take
a bite;instead, itsimplyscrapes away sawdust-like particles.
Scraping produces heat, which can glaze, burn, or mar the
cut-- in extreme cases, can even overheat the bit so as to
destroy itshardness.
In addition, it ismore difficult to control a router when the bit
isscraping instead of cutting.With practically no load on the
motor the bit will be revolving at close to top RPM, and will
have a much greater than normal tendency to bounce offthe
sides of the cut (especially, if the wood has a pronounced
grain with hard and softareas). As a result, the cut produced
may have rippled, instead of straight sides. See Figure 15.
"Too-slow feeding" can also cause your router to take off in a
wrong direction from the intended line ofcut. Always grasp
and hold your router firmly with both hands when routing.
You can detect "too-slow feeding" by the runaway too-highly
pitched sound ofthe motor;or byfeeling the "wiggle" ofthe bit
in the cut.
PaQe14
OPERATION
DEPTH OF CUT
As previously mentioned, the depth of cut is important be-
cause it affects the rate of feed which, in fLu'n,affects the
quality of a cut (and, also, the possibility of damage to your
bit). A deep cut requires a slower feed than a shallow one, and
a too deep cut will cause you to slow the feed so much that
the bit is no longer cutting, it is scraping, instead.
Making a deep cut is never advisable. The smaller bits --
especially those only 1/16 in. in diameter-- are easily broken
off when subjected to too much side thrust. A large enough bit
may not be broken off, but if the cut is too deep a rough cut
will result -- and it may be very difficult to guide and control
the bit as desired. For these rea_sona,we recommend that
several passes be made to reach deeper cuts. See Figure 16.
To make deeper cuts it is therefore necessary to make as
many successive passes as required, lowering the bit for
each new pass. In order to save time, do all the cutting
necessary at one depth setting, before lowering the bit for the
next pass. This will also assure a uniform depth when the final
pass is completed. See Figure 17.
DIRECTION OF FEED AND THRUST
See Figure 18.
The router motor and bit revolve in a clockwise direction. This
gives the tool a slight tendency to twist (in your hands) in a
counterclockwise direction, especially when the motor revs
up (as at starting).
Because of the extremely high speed of bit rotation during a
"proper feeding" operation, there is very little kickback to
contend with under normal conditions. However, should the
bit strike a knot, hard grain, foreign object, etc. that would
affect the normal progress of the cutting action, there will be
a slight kickback-- sufficient to spoil the trueness of your cut
if you are not prepared. Such a kickback is always in the
direction opposite to the direction of bit rotation.
To guard against such a kickback, plan your set-up and
direction of feed so that you will always be thrusting the tool
-- to hold it against whatever you are using to guide the cut
-- in the same direction that the leading edge of the bit is
moving. Inshort, the thrust should be in a direction that keeps
the sharp edges of the bit continuously biting straight intonew
(uncut) wood.
ROUTING
Whenever you are routing a groove, your travel should be in
a direction that places whatever guide you are using at the
right-hand side. In short, when the guide is positioned as
shown in the first part of Figure 19, tool travel should be left
to rightand counterclockwise aroundcurves. When the guide
is positioned as shown in the second part of Figure 19 tool
travel should be right to left and clockwise around curves. If
there is a choice, the first set-up is generally the easiest to
use. In either case, the sideways thrustyou use isagainst the
guide,

EDGE ROUTING
Place router on workpiece, making sure the router bit does
not contact workpiece. Turn router on and let motor buildto
its full speed. Begin your cut, gradually feeding cutter into
workpiece.
WARNING:
Upon completion of cut, turn'motor off and let it come to e
complete stop before removing router from work surface.
WARNING:
Never pull router out of work and place upside down on
work surface before the cutter stops.
EDGING WITH PILOT BITS
See Figure 20.
Rabbets and molded edges can be cut using pilotedcutters.
The pilot extends below the cutter. Some pilots are solid
extensions of the cutter. Others are ball bearing guides that
are fastened to the end of the cutter. The pilots allow the
cutterstotum while thepilotfollowsthe edge oftheworkpiece.
Arbor-type bitswith pilots are excellent for quick, easy, edge
shaping. They will follow workpiece edges that are either
straight or curved. The pilot prevents the bit from makingtoo
deep a cut; and holding the pitotfirmly in contact with the
workpiece edge throughout prevents the cut from becoming
too shallow.
Whenever the workpiece thickness together withthe desired
depth of cut (as adjusted by router depth setting) are such
that only the top part of the edge isto be shaped (leaving at
leasta 1/16in. thick uncutportionat bottom), the pilotcan ride
against the uncut portion, which will serve to guide it. See
Figure 20. However, ifthe workpiece istoo thin or the bit set
too low so that there will be no uncut edge to ride the pilot
against, an extra board to act as a guide must be placed
under the workpiece. This "guide" board must have exactly
the same contour -- straight or curved -- as the workpiece
edge. If it is positioned so that its edge is flush with the
workpiece edge, the bit willmake a full cut (inas far as the bit
radius).On theother hand, ifthe guide ispositionedas shown
in Figure 20 (out from the workpiece edge), the bitwill make
lessthan a full cut-- which willalter the shape ofthe finished
edge.
NOTE: Ifdesired, any ofthe pilotedbits can be used without
a pilotfor edge shaping with guides, as preceding. Also, the
size (diameter) of the pilot that is used determines the
maximum cut width that can be made with the pilot against
the workpiece edge (the small pilotexposes all of the bit; the
large one reduces this amount by 1/16 in).

OPERATION
ROUTING GROOVES
See Figure 22.
When muting across the face ofboards, set muter at desired
depth ofcut, place the edge of routerbase againstworkpiece,
and turn on your router. Slowly feed the cutter into the
workpiece along desired cutline.
WARNING:
When routing straight cuts across stock, clamp a straight-
edge to the workpiece to use_'as a guide. Position the
straightedge parallel to the cutline and offset the distance
between the cutting edge of the cutter and the edge of the
router base. Hold the router base against the straightedge
and rout the groove.
When routing a groove wider than the diameter of the cutter,
clamp a straightedge on both sides of the cutting line.
Position both guides parallel to the desired cutline and
spaced equal distances from the desired edges ofthe groove.
Rout along one guide; then, reverse direction and rout along
the other guide. Clean out any remaining waste in the center
of the groove freehand.
OPTIONAL EDGE GUIDE A'n'ACHMENT
See Figures 23, 24, and 25.
ROUTING WITH OPTIONAL EDGE GUIDE
See Figures 23 and 24.
Straight cuts and grooves can be routed using an optional
edge guide attachment that may be purchased for use on
your router. The edge guide attaches to a guide holder, then
the guide bars fit into openings in the router base. Knob
screws in the base secure the guide bars in position.
Adjustments are made by loosening the wing bolt on guide
holder, placing the edge guide the desired distance from the
cutter, then retightening wing bolt. Fine adjustments can be
made with edge guide adjustment knob on the end of guide
holder. When routing with the edge guide attachment, hold
edge guide against the edge of workpiece as shown in figure
24.
ROUTING CIRCLES WITH OPTIONAL EDGE
GUIDE
See Figure 25.
The optional edge guide attachment can also be used for
routing circles when a piloted bit is not available or inad-
equate for the required job. Position the edge guide so that
the cutter is in the center opening of the edge guide. Keep
both corners of edge guide pressed against the edge to
maintain a consistent shape.
When routing the outside edge (perimeter) of a circle, feed
the router counterclockwise. When routing the inside of a
circle feed the router clockwise as shown in figure 25.
Remember that the rotation of the bit must always lead into
the workpiece rather than away from it.

ROUTING WITH OPTIONAL ROLLER GUIDE
See Figures 26 and 27.
An optional roller guide is available for use with your router.
Itisuseful for routing uneven edges and trimming laminates.
The roller guide attaches to the guide holder as shown in
figure 26. Itcan beadjusted inand out aswell as upand down.
The rollerguide ridesagainst the uncutedge oftheworkpiece.
When routinga decorative groove along an uneven edge, the
distancefrom rollerguide tocutter should bethe same as the
distance from the desired cut and the edge of theworkpiece.
Fine adjustments can be made with the edge guide adjust-
ment knob on guide holder. Tighten wing bolts securely.
When routing, keep roller pressed tight against edge of
workpiece. Carefully follow desired line of cut so that the
distance between the cut and the edge does not vary.
When trimming laminates with the rollerguide, use a straight
cutting bit or a roundnose bit. Position the rollerguide even
with the inside cutting edge of router bit. The roller guide
follows the edge of the workpiece while the bit trims off the
overhanging laminate. See Figure 27.
ROUTING WITH OPTIONAL GUIDE BUSHINGS
See Figures 28 and 29.
You can accurately duplicate curves and complex shapes by
fitting your router with optional template guide bushing that
extends below the subbase. The router bit passes through
the guide bushing. The guide bushing then rides against a
template.
TO INSTALL TEMPLATE GUIDE BUSHING:
1. UNPLUG YOUR ROUTER.
Failure to unplug your router could result in accidental
starting causing serious injury.
2. Place router upside down on workbench.
3. Place template guide bushing in recessed portion of
router base as shown in figure 28.
4. Align the cutouts in guide bushing with threaded holes
in base.
5. Secure guide bushing to router base with roundhead
screws provided.
6. Tighten screws securely.

FREEHAND ROUTING
See Figure 30.
When used freehand, your plunge router becomes a flexible
and versatile tool. This flexibility makes itpossible to easily
routsigns, relief sculptures, etc.
There are two basic techniques for freehand routing:
1. Routing letters, grooves, and patterns intowood.
2. Routing out the background, leaving the letters or pat-
tern raised above the surface as shown in figure 30.
When freehand rouUng, we suggest the following:
1. Draw or layout the pattern on workpiece.
2. Choose the appropriate cutter. NOTE: A core box or
V-groove bit is often used for routing letters and en-
graving objects. Straight bits and ball mills are often
used to make relief carvings. Veining bits are used to
carve small, intricate details.
3. Rout the pattern in two or more passes. Make the first
pass at 25% of the desired depth of cut. This will
provide better control as well as being a guide for the
next pass.
Freehand routing is an excellent example of how to use
the plunge routing feature of your router:
1. Choose the appropriate cutter, set desired depth of
cut, carefully check set-up, and secure workpiece.
2. Make a test cut ina scrap piece ofwood from the same
workpiece if possible.
3. Depress plunge release actuator and raise cutter from
any preset depth of cut. This also permits raisingcutter
inside router subbase.
4. Place router on workpiece inside pattern to be routed.
5. Grasp handles securely and depress on-off trigger to
start your router.
6. Let motor build to full speed, then gradually plunge
cutter into workpiece until stop bar comes into contact
with stop screw on depth stop block.
7. Squeeze plunge lock actuator to secure depth of cut
setting.
8. Begin routing out the pattern, continuing until a com-
plete pass at this depth of cut has been made.
